**Question:**x=-2 and I've tried plugging it in and can't get it to work. Any help or thoughts would be greatly appreciated. maybe x doesnt really equal -2 and it's a trick.

thanks in advance.

**Answers:**

Watch:

2(-2-3) -3(-2+5) = 3(-2-2)-7

2(-2 + -3) -3(3) = 3 [(-2+(-2)] -7

2 (-5) - 9 = 3 (-4) -7

-10 - 9 = -12 -7

-10 + (-9) = -12 + (-7)

-19 = -19

the mistake I made the first time I did it was in the part 3(-2 -2)

X does equal -2.

You just need to learn your integer rules.

ie. negative times negative = positive

and so on and so on.

2x-6-3x-15=3x-6-7 -x-21=3x-13 4x=-34 x=-8.5
